Specification of Letters Patent. Patented Dec. 13, 1910.

Application tiled .Tune 17, 1908. v Serial No. 438,913.

Be it known that I, DE ELBnn'r A. REY- NOLDS, a citizen of the United States of America, and a resident of New York, county of New York, State of New York,

, have invented certain new and useful Improvements in Concrete Constructions, of which the following is a specification, reference being had to the accompanying drawing/, forminma part thereof.

1:` y invention relates to improvements 1n concrete constructions, and particularly to an lmproved form and construction of reinforced concrete pole.

The main object of my invention is to improve, simplify and lessen the cost of manufacture of reinforced concrete poles such as may conveniently be employed for signal posts,.lamp posts, electric wire poles and other, purposes; and to these ends my invention consists first in a novel -form and yconstruction of the reinforcement therefor may extend laterally beyond the face of the pole when it is completed, such steps constituting means for factilitating the ascent and descent of the pole on the part of oper- 4at-ors and linemen.

My invention also consists in providing a metallic piping disposed longitudinally through the pole, such piping adapted to form reinforcing means, and also, when de'- sired, a conduit through which air or other n,gases under pressure may be conveyed. In

connection with this longitudinal piping, I may conveniently employ short sectionsof branch pipes, arranged to project laterally from the pole, such lbranch pipes being convenlently disposed for the purpose of constituting steps. or for providing means for supporting a ladder; or suchbranch pipes may, if desired, be employed for the purpose of conveying the air or other gases under pressure from the longitudinal conduit to any point at which it may be required for use.

In order that my invention may be fully understood, I will now proceed to describe an embodiment thereof, having reference to ythe accompanying drawings illustrating the same and will then point out the novel features in claims. 4

In the drawin sz--Figure 1 is awview in side elevation o a pole constructed in accordance with my' inventioin Fig. 2 is'an enlarged view in horizontal section upon the plane of line 2--2 of Fig. 1. Fig.y 3 is a view in horizontal section upon the plane of line 3--3 of Fig. 1. Fig. 4 is a face view of the stamping employed for the purpose of reinforcement, showing the same before it has beenbent into .structural or framework form. Fig. 5 is a view in perspective of the same after it has been bent into form to constitute the framework and ready to be employed in the production of a pole.

The pole shown in Fig. 1 comprises a main body portion 10 of concrete, a reinforcing structure 11 and a central pipe or conduit 12. The reinforcing structure 11 comprises four upriglits 13, (see particularly Fig. 5) connected together by central arms 14.l The structure 11 is made from a stamping, a portion of which is shown in Fig. 4. This stamping may, it will be noted, be produced from a piece of sheet metal, such piece of sheet metal being for ordinary purposes, about 12 inches in width, and `about 9,-, of an inch thick, though it may, ofcourse, be of other dimensions as to width and thickness. The stamping and structure are made of a proper length in accordance with the height of pole required. Figs. 4 and 5 illustrating but comparatively short sections thereof. In the stamping, it will be seen that the uprights 13 11e quite close to each other and are connected by the arms 14 which at this time lie parallel with the said uprights. In forming the frame work, the uprights 14 are pulled apart so as to bring the arms 14 to a substantially horizontal condition. the alternate uprights being lowered with respect to the ones between them, a distance about equal to the length of the said arms. After the uprights have been thus separated, the arms are further bent so that they will extend at right angles to each other when viewed horizontally, so as to form a substantially rectangular structure with an upright at each corner thereof. The last arm 14 will, ef course, have a free end, and I provide the upright farthest away therefrom when in the conditionshown in Fig. 4) with an opening 15 for receiving the end of such arm14, the said opening and the end of the arm 14a being arranged to come into register when the -parts are bent so as v to form the structure shown in Fig. 5. It will be lseen from the foregoing, that the framework of Fig. 5,'which 1s to be used as reinforcing means, isa complete integral and rigid structure. Thus in making the pole, this reinforcing structure may be set in a mold such as is employed in the production of cast concrete objects, and the'concrete then inserted freely without there being any liability of the reinforcement becoming disarranged. This is very advantageous, for in the past, great difficult has been experienced in holding the di erent elements which have'constituted the reinforcement, in position while the process of casting;` was being carried out.

It is' common to provide long posts or poles with lateral projecting steps by which ascent or descent thereof on the part of operators, linemen etc., is facilitated. For

the purpose of making provision for such steps, I have provided the stamping with arms 16 arranged longitudinally intermediate the sets of arms 14, such arms 16 being arranged to project from such uprights as come opposite to each other when the stamp\ ing is bent to form the aforementioned structure, and I preferably make these arms 16 of such length that they maybe vconveniently bentbackward upon themselves after 'having been properly bent to project laterally7 from the structure as is shown in Fig. 5, the said arms being provided with a? slight projection as at'17 to form the usual abutment, such as is generally employed in these steps for preventing the user from slipping endwise therefrom. The 'free end of that portion of the step which is turned backupon itselfis received within the concrete body of the. pole so that the step acquires a double support, and is hence rigidly and firmly held in position.

The central piping 12 (see Figs. 1, 2 and 3), also constitutes a reinforcing means, and when employedlends strength to the post or pole as a Whole, but the said piping may be emplo ed where desired to convey air or gases un er4 ressure therethrough in addition to its ot er functions. Furthermore it may be provided with short branches 18 whlch may `constitute steps and mayjalso be provided with one orl more longer branches 19 to constitute means for supporting a ladder in proximityto the pole.

The ends of the branches and of the central conduit may be closed by caps 20 and where the iping` is intended-to be used to convey flui one or more of these caps may be removed and the proper connection made as will be well understood.

In producing the stam ing, the various portions thereof may be s ightly curved, if desired,` as is illustrated in the drawin whereby to lend additional rigidity to t e reinforcing structure and -to various elet ments thereof.

What I claim is:

1. A reinforcement for cast concrete poles comprising an expanded metal structure formed from a stamping includin rality of uprights with arms whic lie between them and are connected at their opposite ends with adjacent u ri hts at oints in saidadja'centu rightswhich eforet estructure is expan ed are in staggered relation, the said structure being expanded and formed by drawing the uprights apart and bending the arms so that the said uprights are re ularly disposed around a central axis, one o the outer uprights being provided with openings, and the other outer upright havin arms on the outside thereof ywhlch have ee ends, such free ends being adapted to be received in the 4said openings, substantiallyas set forth. Y

2. A reinforcement stamping for cast concrete poles comprising a plurality of `u f rights 13, arms 14 connecting them, t e ends of the said arms connectlng with the adjacent upri hts at points in staggered relation, one oft e outer uprights havlng openings 15, and the other of the said outer u ri hts having arms 14a with free ends, tv e said uprights also provided with free ended arms 16 connected thereto at points intermediate the points of connection of the said arms 14.

3. A reinforcement stamping for cast concrete poles comprising a, plurality of up* rights, sets -of connecting arms therefor, the arms of'each set connected at their opposite ends with adjacent uprights at points in staggered relation, whereby the structure may be expanded, and free ended arms connected to the said uprights longitudinally intermediate the said sets of connecting arms.
